Revised 10/14
Problem Possible Cause
Aux (No.) Sensor 1. Disconnection between
Open Aux connector and ASU.
2. Aux sensor harness un-
plugged from the V6 Tem-
perature Module.
3. Aux sensor circuit
inoperative.
Aux (No.) Sensor 1. Debris at connection
Short between Aux and ASU.
2. Debris at V6 Temperature
Module.
3. Aux sensor circuit
inoperative.
Solution
1. Visually examine connector for proper-
contact and seating. If pins or housings
are damaged, repair or replace Aux har-
ness (in ASU).
2. Verify that affected Aux is properly
connected to Temp Module. Replace or
repair damaged Aux harness as neces-
sary.
3. Replace Aux sensor if resistance does
not comply with r esistance table. Use
schematic to check Aux sensor resistance
at ASU socket, repair or replace A ux,
Aux harness or Temperature Module as
appropriate.
1. Visually inspect Aux plug and ASU
socket for cleanliness and proper contact
and seating of pins.
2. Visually inspect that the affected Aux
plug at the Temperature Module is clean
and properly installed.
3.Using the schematic, check Aux sensor
resistance at ASU socket. An ohmmeter
can also be used to isolate a pinched wire
in the Aux harness. When cause is isol-
ated, repair or replace sensor, Aux, Aux
harness or the Temperature Module as
appropriate.
